Connects, reads the greeting, says EHLO, and QUITs, timing it all. A greeting other than 220, such as 554 for refusing, a EHLO not answered with 250, or a extension asked for not being offered, is CRITICAL, as is not being able to connect.
With --starttls, STARTTLS must be offered, and is done, with EHLO said again over TLS. With --ssl, it connects over TLS from the start, as for port 465. The certificate is checked unless --insecure is given. See Monitoring::Sneck::Checks::https_cert with --starttls smtp for when it expires.
